Abstract
INTRODUCTION This study aims to investigate the ability of umbilical cord mesenchymal stem cells (UC-MSC) to enhance the regeneration of pulp-dentin complex in immature permanent teeth with irreversible pulpitis. METHODS A total of 32 mandibular premolar teeth with immature apices in 5 dogs were used in this in-vivo randomized controlled trial (RCT). Eight healthy teeth without pre-existing pathosis served as the positive control samples and received no treatment, while in another 8 teeth, the pulp was completely extirpated (negative control). Class V cavities were prepared to induce inflammation in the remaining 16 teeth (groups 3 and 4) and the pulp was extirpated 2-4 mm short of the radiographic apex. Of the 16, the 8 teeth in group 4 received 1 mL of cord blood stem cells with a hydrogel scaffold. Blood clots were covered with mineral trioxide aggregates at the cementoenamel junction in the experimental groups, and teeth were filled with RMGI and composite. Three months later, block sections were removed for histologic evaluations for the evaluation of postoperative apical closure, degree of inflammation, and presence of normal pulp tissue. The data were statistically analyzed with the chi-square test (P < .05). RESULTS All teeth with complete pulp extirpation demonstrated pulpal necrosis with no postoperative closure of their apices, while apical closure was seen in all the teeth in the remaining groups. There was a statistically significant (P < .001) difference in the presence of inflammation and normal pulp tissue between the experimental groups. The teeth in group 3 showed normal pulp tissue extending to the level of MTA, but there was inflammation within the canal space. In contrast, the teeth in the UC-MSC group demonstrated organized, normal pulp tissue with no inflammation. CONCLUSION Based on these results, the regeneration of the pulp-dentin complex is possible with no inflammation when UC-MSCs are used and 2-4 mm of the apical pulp remains intact in immature teeth with irreversible pulpitis.

Abstract
OBJECTIVE The collagen-induced arthritis (CIA) model is the most commonly studied autoimmune model of rheumatoid arthritis (RA). In this study, we investigated the usefulness of collagen type II emulsified in Freund's incomplete adjuvant (CII/IFA) as a suitable method for establishing RA in Lewis rats. The aim of the present study was to present a straightforward and effective method for inducing CIA in rats. MATERIALS AND METHODS In this experimental study, animals were divided into two equal groups (n=5); control and CIA. Five rats were injected intradermally at the base of the tail with a 0.2 ml CII/IFA emulsion. On the seventh day, a 0.1 ml CII/IFA emulsion booster was injected. Arthritis symptoms that arose were evaluated at clinical, histological, radiological, and at protein expression levels to find out if the disease had been induced successfully. RESULTS Our finding showed a decreasing trend in the body weight during the RA induction period, while the arthritis score and paw thickness were increased during this period. The results of the enzyme-linked immunosorbent assay (ELISA) for serum samples revealed that the levels of proinflammatory cytokines, interleukin (IL)-1β, IL-6, IL-17, and tumor necrosis factor (TNF)-α and anti-CII IgG were significantly increased in CIA rats compared to the control group. After CIA induction, the level of anti-inflammatory protein IL-10 was decreased significantly. Radiographic examination of the hind paws showed soft tissue swelling, bone erosion, and osteophyte formation in CIA rats. Additionally, based on histological evaluations, the hind paws of the CIA group showed pannus formation, synovial hyperplasia, and bone and cartilage destruction. CONCLUSION It seems that CII/IFA treatment can be an appropriate and effective method to induce RA disease in Lewis rats. This well-established and well-characterized CIA model in female Lewis rats could be considered to study aspects of RA and develop novel anti-arthritic agents.

Abstract
Rheumatoid arthritis (RA) is a chronic and systemic autoimmune disease of unknown etiology. The most common form of this disease is chronic inflammatory arthritis, which begins with inflammation of the synovial membrane of the affected joints and eventually leads to disability of the affected limb. Despite significant advances in RA pharmaceutical therapies and the availability of a variety of medicines on the market, none of the available medicinal therapies has been able to completely cure the disease. In addition, a significant percentage (30-40%) of patients do not respond appropriately to any of the available medicines. Recently, mesenchymal stromal cells (MSCs) have shown promising results in controlling inflammatory and autoimmune diseases, including RA. Experimental studies and clinical trials have demonstrated the high power of MSCs in modulating the immune system. In this article, we first examine the mechanism of RA disease, the role of cytokines and existing medicinal therapies. We then discuss the immunomodulatory function of MSCs from different perspectives. Our understanding of how MSCs work in suppressing the immune system will lead to better utilization of these cells as a promising tool in the treatment of autoimmune diseases.

Abstract
AIM Parkinson's Disease (PD) is a common age-related neurodegenerative disorder with a rising prevalence. Human pluripotent stem cells have emerged as the most promising source of cells for midbrain dopaminergic (mDA) neuron replacement in PD. This study aimed to generate transplantable mDA progenitors for treatment of PD. MATERIALS AND METHODS Here, we optimized and fine-tuned a differentiation protocol using a combination of small molecules and growth factors to induce mDA progenitors to comply with good manufacturing practice (GMP) guidelines based on our clinical-grade human embryonic stem cell (hESC) line. KEY FINDINGS The resulting mDA progenitors demonstrated robust differentiation and functional properties in vitro. Moreover, cryopreserved mDA progenitors were transplanted into 6-hydroxydopamine-lesioned rats, leading to functional recovery. SIGNIFICANCE We demonstrate that our optimized protocol using a clinical hESC line is suitable for generating clinical-grade mDA progenitors and provides the ground work for future translational applications.

Abstract
In many multicellular organisms, mature gametes originate from primordial germ cells (PGCs). Improvements in the culture of PGCs are important not only for developmental biology research, but also for preserving endangered species, and for genome editing and transgenic animal technologies. SMAD2/3 appear to be powerful regulators of gene expression; however, their potential positive impact on the regulation of PGC proliferation has not been taken into consideration. Here, the effect of TGF-β signaling as the upstream activator of SMAD2/3 transcription factors was evaluated on chicken PGCs' proliferation. For this, chicken PGCs at stages 26-28 Hamburger-Hamilton were obtained from the embryonic gonadal regions and cultured on different feeders or feeder-free substrates. The results showed that TGF-β signaling agonists (IDE1 and Activin-A) improved PGC proliferation to some extent while treatment with SB431542, the antagonist of TGF-β, disrupted PGCs' proliferation. However, the transfection of PGCs with constitutively active SMAD2/3 (SMAD2/3CA) resulted in improved PGC proliferation for more than 5 weeks. The results confirmed the interactions between overexpressed SMAD2/3CA and pluripotency-associated genes NANOG, OCT4, and SOX2. According to the results, the application of SMAD2/3CA could represent a step toward achieving an efficient expansion of avian PGCs.

Abstract
OBJECTIVE Animal models provide a deeper understanding about various complications and better demonstrate the effect of therapeutic approaches. One of the issues in the low back pain (LBP) model is the invasiveness of the procedure and it does not mimic actual disease conditions in humans. The purpose of the present study was to compare the ultrasound-guided (US-guided) percutaneous approach with the open-surgery method in the tumor necrosis factor-alpha (TNF-α)-induced disc degeneration model for the first time to showcase the advantages of this recently developed, minimally invasive method. MATERIALS AND METHODS In this experimental study, eight male rabbits were divided into two groups (open-surgery and US-guided). Relevant discs were punctured by two approaches and TNF-α was injected into them. Magnetic resonance imaging (MRI) was performed to assess the disc height index (DHI) at all stages. Also morphological changes (annulus fibrosus, nucleus pulposus) were evaluated by assessing Pfirrmann grade and histological evaluation (Hematoxylin and Eosin). RESULTS The findings indicated targeted discs became degenerated after six weeks. DHI in both groups was significantly reduced (P<0.0001), however the difference was not significant between the two groups. In the open-surgery group, osteophyte formation was seen at six and eighteen weeks after the puncture. Pfirrmann grading revealed significant differences between injured and adjacent uninjured discs (P<0.0001). The US-guided method indicated significantly fewer signs of degeneration after six (P=0.0110) and eighteen (P=0.0328) weeks. Histological scoring showed significantly lower degeneration in the US-guided group (P=0.0039). CONCLUSION The US-guided method developed a milder grade condition and such a model better mimics the chronic characteristics of LBP and the procedure is more ethically accepted. Therefore, the US-guided method could be a merit approach for future research in this domain as a safe, practical and low-cost method.

Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease of unknown cause. The interaction of immune system cells and the secretion of inflammatory cytokines with synovial cells leads to severe inflammation in the affected joints. Currently, medications, including non-steroidal anti-inflammatory drugs, glucocorticoids, and more recently, disease-modifying anti-rheumatic drugs, are used to reduce inflammation. However, long-term use of these drugs causes adverse effects or resistance in a considerable number of RA patients. Recent findings revealed the safety and efficacy of mesenchymal stromal cells (MSCs)-based therapies both in RA animal models and clinical trials. Here, the beneficial effects of bone marrow-derived heterogeneous MSCs (BM-hMSCs) and Wharton jelly-derived MSCs (WJ-MSCs) at early passages were compared to BM-derived clonal MSCs (BM-cMSCs) at high passage number on a rat model of collagen-induced arthritis. Results showed that systemic delivery of MSCs significantly reversed adverse changes in body weight, paw swelling, and arthritis score in all MSC-treated groups. Radiological images and histological evaluation demonstrated the therapeutic effects of MSCs. There was a decrease in serum level of anti-collagen type II immunoglobulin G and the inflammatory cytokines interleukin (IL)-1β, IL-6, IL-17, and tumor necrosis factor-α in all MSC-treated groups. In contrast, an increase in inhibitory cytokines transforming growth factor-β and IL-10 was seen. Notably, the long-term passages of BM-cMSCs could alleviate RA symptoms similar to the early passages of WJ-MSCs and BM-hMSCs. The importance of BM-cMSCs is the potential to establish cell banks with billions of cells derived from a single donor that could be a competitive cell-based therapy to treat RA.

Abstract
Human embryonic stem cells (hESCs) are predisposed to aneuploidy through continual passages. Some reports indicate more sensitivity of aneuploid hESCs cells to anticancer drugs. The present study was designed to investigate the cytotoxicity of three anticancer drugs (including bortezomib, paclitaxel, and lapatinib) and their effect on aneuploidy rate in hESCs. To create a low-level mosaic cell line, normal hESCs (80%) and trisomic hESCs for chromosomes 12 and 17 (20%) were mixed. The effect of the 3 mentioned anticancer drugs on the chromosomal status was assessed by metaphase spread analysis after selection of the nontoxic conditions. Expression of pluripotency genes was analyzed, and an alkaline phosphatase test was performed to assess pluripotency preservation. Our data showed that treatment with bortezomib, paclitaxel, and lapatinib was nontoxic at 0.01, 0.01, and 0.2 μM concentrations, respectively. Alkaline phosphatase and pluripotency gene expression analyses revealed maintenance of pluripotency following treatment with above-noted nontoxic concentrations. Aneuploid cells were dominant in treated and control groups with a minimum abundance of 70%, with no significant differences between groups. Drug treatments had no negative effect on pluripotency. Insensitivity of aneuploid cells in treatment groups could be related to the specific characteristics of each cell line in response to the drug and the proliferative superiority of cells with trisomies 12 and 17.

Abstract
INTRODUCTION Mesenchymal stromal cells (MSCs) have opened a new window to treat inflammatory and non-inflammatory diseases. Nonetheless, their clinical applications require rigorous control and monitoring procedures to ensure full compliance with the principles of good manufacturing practice (GMP). Various evaluations should be passed in conjunction with the development of these newly emerging therapeutic products from bench-to-bedside. These evaluations include in vitro characterization, preclinical studies, and clinical trials to ensure product safety and efficacy. Therefore, a robust and well-designed preclinical study is critical to confirm product safety. This study aims to determine the probable toxicity effects of local and systemic injections of cryopreserved human bone marrow-derived clonal MSCs (BM-cMSCs) during subacute and subchronic periods of time. METHODS BM-cMSCs were characterized according to the International Society for Cell and Gene Therapy (ISCT) criteria for MSCs. Both safety and toxicity of the BM-cMSCs population produced under GMP-compatible conditions were assessed in both sexes of Sprague Dawley (SD) rats via systemic intravenous (IV) administration and local injection in intervertebral disc (IVD). Behavioral changes, clinical signs of toxicity, and changes in body weight, water and food consumption were the important variables for product toxicity testing over 14 consecutive days during the subacute period and 90 consecutive days during the subchronic period. At the end of the assessment periods, the rats were killed for histopathology analysis of the target tissues. The BM-cMSCs potential for tumorigenicity was checked in nude mice. RESULTS Single IV and IVD injections of BM-cMSCs did not cause significant signs of clinical toxicity, or changes in laboratory and histopathology data during the subacute (14 day) and subchronic (90 day) periods. Ex vivo-expanded and cryopreserved BM-cMSCs did not induce tumor formation in nude mice. CONCLUSION The results suggest that local and systemic administrations of xenogeneic BM-cMSCs in both sexes of SD rats do not cause toxicity during the subacute and subchronic periods of time. Also, BM-cMSCs were non-tumorigenic in nude mice.

Abstract
Human otic organoids generated from pluripotent stem cells (PSCs) provide a promising platform for modeling, drug testing, and cell-based therapies of inner ear diseases. However, providing the appropriate niche that resembles inner ear development and its vasculature to generate otic organoids is less conspicuous. Here, we devised a strategy to enhance maturation of otic progenitor cells toward human hair cell-like cells (HCLCs) by assembling three-dimensional (3D) otic organoids that contain human PSC-derived otic cells, endothelial cells, and mesenchymal stem cells (MSCs). Heterotopic implantation of otic organoids, designated as grafted otic organoids (GOs), in ex ovo chick embryo chorioallantoic membrane (CAM) stimulated maturation of the HCLCs. Functional analysis revealed the presence of voltage-gated potassium currents without detectable sodium currents in these cells in the GOs. Our results demonstrated that implantation of 3D heterotypic cell mixtures of otic organoids improved maturation of human HCLCs. This GO-derived HCLCs could be an attractive source for drug discovery and other biomedical applications.

Abstract
AIMS Immunomodulation concurrent with the promotion of β-cell function is a strategy used to develop innovative therapies for type 1 diabetes (T1D). Here, we assessed the therapeutic potential of co-administration of human clonal mesenchymal stem (stromal) cells (hBM-cMSCs) and liraglutide as a glucagon-like peptide-1 agonist in a non-human primate model with streptozotocin (STZ)-induced diabetes. MAIN METHODS Diabetes was induced through intravenous (i.v.) multiple low-dose (MLD) infusions of STZ at a dose of 30 mg/kg body weight (b.w.) for five consecutive days, followed by two booster injections of 35 mg/kg on days 12 and 19. After 90 days, the diabetic animals were randomly allocated to two groups: The combination therapy group (n = 4) received injections of 1.5 × 106 hBM-cMSCs/kg b.w. through celiac artery by angiography on days 91 and 105 and daily subcutaneous injections of liraglutide (up to 1.8 mg/day) until day 160 while vehicle group received phosphate-buffered saline. The monkeys were assessed for functional, immunological, and histological analysis. KEY FINDINGS The combined treatment group had continued reduction in FBG levels up to day 160, which was accompanied by increased b.w., C-peptide, and β-cell function, and decreased HbA1c and fructosamine levels compared to vehicle group. The combined treatment increased Tregs, IL-4, IL-10, and TGF-β1 and decreased IL-6 and IL-1β. Stereological analysis of the pancreatic tissue exhibited more total volume of insulin-secreting islets in the combined treatment group compared to vehicle group. SIGNIFICANCE Our findings demonstrated this combined treatment impaired the clinical symptoms of diabetes in this animal model through immunomodulation and β-cell preservation.

Abstract
INTRODUCTION Pluripotent stem cells (PSCs) are promising tools for modern regenerative medicine applications because of their stemness properties, which include unlimited self-renewal and the ability to differentiate into all cell types in the body. Evidence suggests that a rare population of cells within a tumor, termed cancer stem cells (CSCs), exhibit stemness and phenotypic plasticity properties that are primarily responsible for resistance to chemotherapy, radiotherapy, metastasis, cancer development, and tumor relapse. Different therapeutic approaches that target CSCs have been developed for tumor eradication. RESULTS AND DISCUSSION In this review, we first provide an overview of different viewpoints about the origin of CSCs. Particular attention has been paid to views believe that CSCs are probably appeared through dysregulation of very small embryonic-like stem cells (VSELs) which reside in various tissues as the main candidate for tissue-specific stem cells. The expression of pluripotency markers in these two types of cells can strengthen the validity of this theory. In this regard, we discuss the common properties of CSCs and PSCs, and highlight the potential of PSCs in cancer studies, therapeutic applications, as well as educating the immune system against CSCs. CONCLUSION In conclusion, the resemblance of CSCs to PSCs can provide an appropriate source of CSC-specific antigens through cultivation of PSCs which brings to light promising ideas for prophylactic and therapeutic cancer vaccine development.

Abstract
Human pluripotent stem cells (hPSCs) are commonly kept in a primed state but also able to acquire a more immature naive state under specific conditions in vitro. Acquisition of naive state changes several properties of hPSCs and might affect their contribution to embryonic development in vivo. However, the lack of an appropriate animal test system has made it difficult to assess potential differences for chimera formation between naive and primed hPSCs. Here, we report that the developing chicken embryo is a permissive host for hPSCs, allowing analysis of the pluripotency potential of hPSCs. Transplantation of naive-like and primed hPSCs at matched developmental stages resulted in robust chimerism. Importantly, the ability of naive-like but not of primed hPSCs to form chimera was substantially reduced when injected at non-matched developmental stages. We propose that contribution to chick embryogenesis is an informative and versatile test to identify different pluripotent states of hPSCs.

Abstract
Chromosomal abnormalities, as a frequent phenomenon in cultured embryonic stem cells (ESCs), is a major obstacle in the ESC application in regenerative medicine. Recent studies showed that aneuploid embryonic stem cells of humans and mice are more vulnerable to anticancer drugs, compared with normal cells. The aim of the current study was to evaluate effects of three anticancer drugs, paclitaxel, lapatinib and bortezomib, on mouse embryonic stem cells (mESCs) as a suitable and available model. To assess in vitro cell toxicity, two mESC lines were treated with the aforementioned drugs. Using G-band karyotyping and micronucleus assay, the effect of anticancer drugs in terms of reduction of chromosomal instability in the mESCs was evaluated in control and treatment groups. Also, apoptosis rate of both groups was estimated by FITC-Annexin V/Propidium Iodide (PI) double staining. In addition, the effect of these three drugs in maintaining the pluripotency was assessed through alkaline phosphatase assay and quantification of the expression of three key pluripotency genes, Nanog, Pou5f1 and Sox-2 was performed using Real Time PCR. The rate of numerical abnormalities after treatment with paclitaxel and lapatinib was lower than the control group. The expression level of pluripotency genes exhibited no significant difference between control and treatment groups. Administration of paclitaxel and lapatinib to the mESCs culture at an appropriate dose and in a timely manner could decrease chromosome stability without affecting pluripotency.

Abstract
BACKGROUND Premature ovarian failure (POF) affects many adult women less than 40 years of age and leads to infertility. According to previous reports, various tissue-specific stem cells can restore ovarian function and folliculogenesis in mice with chemotherapy-induced POF. Human embryonic stem cells (ES) provide an alternative source for mesenchymal stem cells (MSCs) because of their similarities in phenotype and immunomodulatory and anti-inflammatory characteristics. Embryonic stem cell-derived mesenchymal stem cells (ES-MSCs) are attractive candidates for regenerative medicine because of their high proliferation and lack of barriers for harvesting tissue-specific MSCs. However, possible therapeutic effects and underlying mechanisms of transplanted ES-MSCs on cyclophosphamide and busulfan-induced mouse ovarian damage have not been evaluated.
AIM To evaluate ES-MSCs vs bone marrow-derived mesenchymal stem cells (BM-MSCs) in restoring ovarian function in a mouse model of chemotherapy-induced premature ovarian failure.
METHODS Female mice received intraperitoneal injections of different doses of cyclophosphamide and busulfan to induce POF. Either human ES-MSCs or BM-MSCs were transplanted into these mice. Ten days after the mice were injected with cyclophosphamide and busulfan and 4 wk after transplantation of the ES-MSCs and/or BM-MSCs, we evaluated body weight, estrous cyclicity, follicle-stimulating hormone and estradiol hormone concentrations and follicle count were used to evaluate the POF model and cell transplantation. Moreover, terminal deoxynucleotidyl transferase mediated 2-deoxyuridine 5-triphosphate nick end labeling, real-time PCR, Western blot analysis and immunohistochemistry and mating was used to evaluate cell transplantation. Enzyme-linked immunosorbent assay was used to analyze vascular endothelial growth factor, insulin-like growth factor 2 and hepatocyte growth factor levels in ES-MSC condition medium in order to investigate the mechanisms that underlie their function.
RESULTS The human ES-MSCs significantly restored hormone secretion, survival rate and reproductive function in POF mice, which was similar to the results obtained with BM-MSCs. Gene expression analysis and the terminal deoxynucleotidyl transferase mediated 2-deoxyuridine 5-triphosphate nick end labeling assay results indicated that the ES-MSCs and/or BM-MSCs reduced apoptosis in the follicles. Notably, the transplanted mice generated new offspring. The results of different analyses showed increases in antiapoptotic and trophic proteins and genes.
CONCLUSION These results suggested that transplantation of human ES-MSCs were similar to BM-MSCs in that they could restore the structure of the injured ovarian tissue and its function in chemotherapy-induced damaged POF mice and rescue fertility. The possible mechanisms of human ES-MSC were related to promotion of follicular development, ovarian secretion, fertility via a paracrine effect and ovarian cell survival.

Abstract
The ability of human embryonic stem cells (hESCs) to proliferate unlimitedly and give rise to all tissues makes these cells a promising source for cell replacement therapies. To realize the full potential of hESCs in cell therapy, it is necessary to interrogate regulatory pathways that influence hESC maintenance and commitment. Here, we reveal that pharmacological attenuation of p38 mitogen-activated protein kinase (p38-MAPK) in hESCs concomitantly augments some characteristics associated with pluripotency and the expressions of early lineage markers. Moreover, this blockage capacitates hESCs to differentiate towards an endoderm lineage at the expense of other lineages upon spontaneous hESC differentiation. Notably, hESCs pre-treated with p38-MAPK inhibitor exhibit significantly improved pancreatic progenitor directed differentiation. Together, our findings suggest a new approach to the robust endoderm differentiation of hESCs and potentially enables the facile derivation of various endoderm-derived lineages such as pancreatic cells.

Abstract
Sprmatogonial stem cells (SSCs) are valuable for preservation of endangered fish species, biological experimentation, as well as biotechnological applications. However, the rarity of SSCs in the testes has been a great obstacle in their application. Thus, establishment of an efficient in-vitro culture system to support continuous proliferation of SSCs is essential. The present study aimed to establish an efficient and simple method for in vitro culture of Caspian trout undifferentiated spermatogonial cells. Using a two-step enzymatic digestion, testicular cells were isolated from immature testes composed of mainly undifferentiated spermatogonial cells with gonadosomatic indices of <0.05%. The spermatogonial cells were purified by differential plating through serial passaging. The purified cells indicated high expression of type A spermatogonia-related genes (Ly75, Gfrα1, Nanos2, Plzf and Vasa). Proliferation of purified cells was confirmed by BrdU incorporation. Co-culture of purified cells with testicular somatic cells as a feeder layer, resulted in continuous proliferation of type A spermatogonia. The cultured cells continued to express type A spermatogonia-specific markers after one month culture. The cultured spermatogonia were successfully incorporated into the germline after being intraperitoneally transplanted into sterile triploid rainbow trout hatchlings. These results, for the first time, demonstrated that the somatic microenvironment of the rainbow trout gonad can support the colonization and survival of intraperitoneally transplanted cells derived from a fish species belonging to a different genus. Therefore, the combination of in vitro culture system and xenotransplantation can be considered as a promising strategy for conservation of Caspian trout genetic resources.

Abstract
Pluripotent cells transiently develop during peri-implantation embryogenesis and have the capacity to convert into three embryonic lineages. Two typical states of pluripotency, naïve and primed, can be experimentally induced in vitro. The in vitro naïve state can be stabilized in response to environmental inductive cues via a unique transcriptional regulatory program. However, interference with various signaling pathways creates a spectrum of alternative pluripotent cells that display different functions and molecular expression patterns. Similarly, human naïve pluripotent cells can be placed into two main levels - intermediate and bona fide. Here, we discuss several culture conditions that have been used to establish naïve-associated gene regulatory networks in human pluripotent cells. We also describe different transcriptional patterns in various culture systems that are associated with these two levels of human naïve pluripotency.

Abstract
BACKGROUND Diabetes is a major worldwide health problem. It is widely accepted that the beta cell mass decreases in type I diabetes (T1D). Accordingly, beta cell regeneration is a promising approach to increase the beta cell mass in T1D patients. However, the underlying mechanisms of beta cell regeneration have yet to be elucidated. One promising avenue is to create a relevant animal model to explore the underlying molecular and cellular mechanisms of beta cell regeneration. The zebrafish can be considered a model in beta cell regeneration studies because the pancreas structure and gene expression pattern are highly conserved between human and zebrafish. MATERIALS AND METHODS In this study, the Tol2 transposase was exploited to generate a Tg(Ins:egfp-nfsB) zebrafish model that expressed a fusion protein composed of enhanced green fluorescent protein (EGFP) and nitroreductase (NTR) under control of the Ins promoter. RESULTS Metronidazole (MTZ) treatment of Tg(ins:egfp-nfsB) zebrafish larvae led to selective ablation of beta cells. Proof-of-concept evidence for beta cell regeneration in the transgenic larvae was observed two days after withdrawal of MTZ. CONCLUSION This study suggests that the Tg(ins:egfp-nfsB) zebrafish can be used as a disease model to study beta cell regeneration and elucidate underlying mechanisms during the regeneration process.

Abstract
OBJECTIVE Human embryonic stem cells (hESCs) have the potential to give rise to all types of cells in the human body when appropriately induced to differentiate. Stem cells can differentiate spontaneously into the three-germ layer derivatives by embryoid bodies (EBs) formation. However, the two-dimensional (2D) adherent culture of hESCs under defined conditions is commonly used for directed differentiation toward a specific type of mature cells. In this study, we aimed to determine the propensity of the Royan hESC lines based on comparison of expression levels of 46 lineage specific markers. MATERIALS AND METHODS In this experimental study, we have compared the expression of lineage-specific markers in hESC lines during EB versus adherent-based spontaneous differentiation. We used quantitative real-time polymerase chain reaction (qRT-PCR) to assess expressions of 46 lineage-specific markers in 4 hESC lines, Royan H1 (RH1), RH2, RH5, and RH6, during spontaneous differentiation in both EB and adherent cultures at 0, 10, and 30 days after initiation of differentiation. RESULTS Based on qRT-PCR data analysis, the liver and neuronal markers had higher expression levels in EBs, whereas skin-specific markers expressed at higher levels in the adherent culture. The results showed differential expression patterns of some lineage-specific markers in EBs compared with the adherent cultures. CONCLUSION According to these results, possibly the spontaneous differentiation technique could be a useful method for optimization of culture conditions to differentiate stem cells into specific cell types such ectoderm, neuron, endoderm and hepatocyte. This approach might prove beneficial for further work on maximizing the efficiency of directed differentiation and development of novel differentiation protocols.

Abstract
Optimization of an in vitro culture that supports blastocyst (BL) development from single blastomeres (SBs) is essential to generate additional embryos for farm animals and humans and unravel the mechanisms that underlie totipotency. In this study, we have examined BL development from SBs that were derived from 2-cell and 4-cell mouse embryos in different media. Moreover, BLs were assessed for inner cell mass (ICM) by staining with Oct4. We found that BL development was improved in a lower volume of medium (1 µL) compared with a higher volume (5 µL). Furthermore, the supplementation of medium with the inhibitors of ERK1/2 and TGFβ (R2i) signaling pathways in 1 µL droplets of T6 medium improved BL development. The co-culture of SBs with intact embryos in the presence of R2i showed more BL development and ICM to trophectoderm cell number ratio in comparison with SB culture and SB group culture. We also observed reduced total cell number, ICM, and trophectoderm cell numbers in all of the SB culture conditions versus intact embryo development. These findings might facilitate the successful generation of additional embryos for biomedical applications and elucidate the mechanisms that underlie totipotency.

Abstract
Pluripotent stem cell (PSC) lines derived from embryonated avian eggs are a convenient platform for production of various recombinant proteins and vaccines. In chicks, both embryonic stem cells (ESC) and embryonic germ cells (EGC) are considered to be pluripotent cells obtained from early blastodermal cells (stage X) and gonadal tissues (stage HH28), respectively. However, the establishment and long-term maintenance of avian PSC lines faces several challenges and differs in efficiency between chick strains. This study aims to determine the effects of PSC culture media, including serum-based and serum-free media as well as various feeder layers, growth factors, and small molecules on derivation and maintenance of avian embryonic derived-PSCs. Our results have shown that among the different culture conditions, N2B27 serum-free medium supplemented with PD0325901 and SB431542, MEK and TGFβ chemical inhibitors, named as R2i and cytokine leukemia inhibitory factor (LIF) improved PSC derivation from stages X- and HH28 embryos. The application of N2B27/R2i + LIF medium validates the effect of defined pluripotency supporting medium on efficient derivation of chick PSCs and facilitates the use of these cells in biotechnology and biobanking of valuable species.

Abstract
Pluripotent cells emanate from the inner cell mass (ICM) of the blastocyst and when cultivated under optimal conditions immortalize as embryonic stem cells (ESCs). The fundamental mechanism underlying ESC derivation has, however, remained elusive. Recently, we have devised a highly efficient approach for establishing ESCs, through inhibition of the MEK and TGF-β pathways. This regimen provides a platform for dissecting the molecular mechanism of ESC derivation. Via temporal gene expression analysis, we reveal key genes involved in the ICM to ESC transition. We found that DNA methyltransferases play a pivotal role in efficient ESC generation. We further observed a tight correlation between ESCs and preimplantation epiblast cell-related genes and noticed that fundamental events such as epithelial-to-mesenchymal transition blockage play a key role in launching the ESC self-renewal program. Our study provides a time course transcriptional resource highlighting the dynamics of the gene regulatory network during the ICM to ESC transition. Transcriptome data indicated a dynamic gene expression during ICM-ESC transition DNA methyltransferases play a prominent role in efficient ESC generation ESCs maintain pre-Epiblast cell identity EMT blockage is required for ESC derivation

Abstract
Low-level laser therapy (LLLT) exhibited biostimulatory effects on fibroblasts viability. Secretomes can be administered to culture mediums by using bone marrow mesenchymal stem cells conditioned medium (BM-MSCs CM). This study investigated the combined effects of LLLT and human bone marrow mesenchymal stem cell conditioned medium (hBM-MSCs CM) on the cellular viability of human dermal fibroblasts (HDFs), which was cultured in a high-glucose (HG) concentration medium. The HDFs were cultured either in a concentration of physiologic (normal) glucose (NG; 5.5 mM/l) or in HG media (15 mM/l) for 4 days. LLLT was performed with a continuous-wave helium-neon laser (632.8 nm, power density of 0.00185 W/cm(2) and energy densities of 0.5, 1, and 2 J/cm(2)). About 10% of hBM-MSCs CM was added to the HG HDF culture medium. The viability of HDFs was evaluated using dimethylthiazol-diphenyltetrazolium bromide (MTT) assay. A significantly higher cell viability was observed when laser of either 0.5 or 1 J/cm(2) was used to treat HG HDFs, compared to the control groups. The cellular viability of HG-treated HDFs was significantly lower compared to the LLLT + HG HDFs, hBM-MSCs CM-treated HG HDFs, and LLLT + hBM-MSCs CM-treated HG HDFs. In conclusion, hBM-MSCs CM or LLLT alone increased the survival of HG HDFs cells. However, the combination of hBM-MSCs CM and LLLT improved these results in comparison to the conditioned medium.

Abstract
The differentiation potential of pluripotent embryonic stem cells (ESCs) can be manipulated via serum and medium conditions for direct cellular development or to maintain a naïve ground state. The self-renewal state of ESCs can thus be induced by adding inhibitors of mitogen activated protein kinase (MAPK) and glycogen synthase kinase-3 (Gsk3), known as 2 inhibitors (2i) treatment. We have used a shotgun proteomics approach to investigate differences in protein expressions between 2i- and serum-grown mESCs. The results indicated that 164 proteins were significantly upregulated and 107 proteins downregulated in 2i-grown cells compared to serum. Protein pathways in 2i-grown cells with the highest enrichment were associated with glycolysis and gluconeogenesis. Protein pathways related to organ development were downregulated in 2i-grown cells. In serum-grown ESCs, protein pathways involved in integrin and focal adhesion, and signaling proteins involved in the actin cytoskeleton regulation were enriched. We observed a number of nuclear proteins which were mostly involved in self-renewal maintenance and were expressed at higher levels in 2i compared to serum - Dnmt1, Map2k1, Parp1, Xpo4, Eif3g, Smarca4/Brg1 and Smarcc1/Baf155. Collectively, the results provided an insight into the key protein pathways used by ESCs in the ground state or metastable conditions through 2i or serum culture medium, respectively.

Abstract
STUDY QUESTION Can transforming growth factor β (TGFβ) inhibition promote ground state pluripotency of embryonic stem cells (ESCs) from single blastomeres (SBs) of cleavage embryos in different mouse stains? SUMMARY ANSWER Small molecule suppression of extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) and TGFβ signaling (designated as R2i) can enhance the generation of mouse ESCs from SBs of different cleavage stage embryos compared with the dual suppression of ERK1/2 and glycogen synthase kinase 3 (GSK3), designated as 2i, regardless of the strain of mouce. WHAT IS KNOWN ALREADY It is known that chemical inhibition of TGFβ promotes ground state pluripotency in the generation and sustenance of naïve ES cells from mouse blastocysts compared with the well-known 2i condition. However, the positive effect of this inhibition on mouse ESCs from early embryonic SBs remains obscure. STUDY DESIGN, SIZE, DURATION We used 155 cleavage-stage mouse embryos to optimize the culture conditions for blastocyst development. Then, to assess the effects of R2i and 2i on ESC generation from SBs, we cultured isolated SBs in 2i and R2i for 10 days. SBs were replated under the same conditions to produce ESCs. In total, 46 embryos and 321 SBs from two- to eight-cell stages were recovered from NMRI and BALB/c mouse strains and used in this study. PARTICIPANTS/MATERIALS, SETTING, METHODS Blastomeres from 2- to 8-cell stage mouse embryos were dispersed and individually seeded into a 96-well plates that included mitotically inactivated feeder cells. ESCs were generated in B27N2 defined medium supplemented with R2i or 2i. Randomly selected ESC lines, generated from SBs of each stage, were assessed for pluripotency and germ-line transmission. MAIN RESULTS AND THE ROLE OF CHANCE We demonstrated that dual inhibition of ERK1/2 and TGFβ (R2i) enhanced efficient blastocyst development and efficient establishment of ESCs from SB of 2- to 8-cell stage mouse embryos compared with the dual inhibition of ERK1/2 and GSK3 (2i) regardless of the embryonic stage and strain of mice. The proportions of SBs that produced ESC were 50-60 versus 20-30%. LIMITATIONS, REASONS FOR CAUTION This study was done with mouse embryos, it is not known whether these findings are transferable to humans. WIDER IMPLICATIONS OF THE FINDINGS These findings resulted in an increased efficiency of ESC generation from one biopsied blastomere for autogeneic or allogeneic matched pluripotent cells without the need to destroy viable embryos. The results also provided information about the developmental capacity of early embryonic blastomeres. STUDY FUNDING/COMPETING INTERESTS This study was funded by grants provided from Royan Institute, the Iranian Council of Stem Cell Research and Technology and the Iran National Science Foundation. The authors have no conflict of interest to declare.

Abstract
Primordial germ cells (PGCs) have the ability to be reprogrammed into a pluripotent state and are defined as embryonic germ cells (EGCs) in vitro. EGC formation is more efficient, has a shorter culture period than somatic cell reprogramming, and does not require exogenous genetic manipulation. Therefore, EGCs are a good model to analyze mechanisms by which committed cells acquire a pluripotent state. In the present study we have attempted to elucidate a more defined and robust protocol that promotes EGC generation through the suppression of transforming growth factor-β (TGF-β) and extracellular signal-regulated kinase (ERK) signaling pathways by SB431542 (SB) and PD0325901 (PD), respectively. Under this condition the efficiency of transformation of PGCs into EGCs was more than the inhibition of glycogen synthase kinase 3 and ERK signaling pathways. Pluripotency of the resultant-derived EGC lines were further confirmed by gene expression, immunofluorescent staining, directed differentiation ability, teratoma formation, and their contribution to chimeric mice and germ-line transmission. These results showed that PGCs from different embryonic stages (E8.5 and E12.5) could be reprogrammed, maintained, and expanded efficiently under feeder- and serum-free chemically defined conditions by dual inhibition of TGF-β and ERK signaling pathways, regardless of the animal's genetic background.

Abstract
STUDY QUESTION Could selected pluripotency-enhancing small molecules (SMs) lead to efficient derivation of human embryonic stem cells (hESCs) from cleavage embryos-derived single blastomeres (SBs)? SUMMARY ANSWER Inhibition of glycogen synthase kinase β (GSK3β) and Rho-associated kinase (ROCK) signaling can enhance the derivation of hESCs from cleavage embryo-derived SBs. WHAT IS KNOWN ALREADY Parameters involved in sustaining the pluripotency of biopsied blastomeres for generating hESCs without causing injury to a viable embryo have remained obscure. This research seeks to improve the culture conditions for increasing the efficiency of deriving hESCs from SBs from cleavage-stage embryos by using SMs. STUDY DESIGN, SIZE, DURATION In order to identify SMs which may enhance hESC generation from SBs, 11 pluripotency-enhancing SMs were screened and CHIR99021 (CH), a GSK3β inhibitor, was selected. To optimize culture condition in hESC generation from SMs, we used ROCK inhibitor Y27632 (Y) and basic fibroblast growth factor in combination with CH or its alternative, Kenpaullone, in different time courses over 12 days. We also assessed a critical time point for CH + Y treatment of cleavage embryos from 4- to 8-cell embryo. In total, 224 embryos and 1607 SBs were used in the study. PARTICIPANTS/MATERIALS, SETTING, METHODS Blastomeres of fair and poor-quality from 6- to 8-cell stage human embryos were mechanically dispersed and individually seeded into a 96-well plate that was precoated with mitotically inactivated feeder cells. Derivation of hESC line from each SB was carried out in hESC defined medium supplemented with SMs. Randomly selected hESC lines were evaluated by immunostaining for pluripotency markers, karyotype analysis and differentiation potential into the three embryonic germ layer derivatives. MAIN RESULTS AND THE ROLE OF CHANCE We found that 3 μM CH was the only SM that was capable of directing SBs from fair and poor-quality 6-8-cell embryos into hESC lines. The application of hESC-conditioned medium had no additive effect on hESC establishment from SBs. Also, we indicated that CH combined with Y improved hESC generation efficiency by up to 31%. By using of Kenpaullone as an alternative to CH, we confirmed the involvement of GSK3 inhibition in hESC derivation from SBs. Interestingly, by treatment of 4-cell embryos, these SMs could enhance the derivation efficiency of SB-derived hESC lines up to 73% and the maximum number of hESC lines from SBs of one embryo was achieved in this state. LIMITATIONS, REASONS FOR CAUTION The low quality of the embryos used in this study most likely had an effect on hESC generation. Furthermore, although we attempted to minimize any differences in inter-embryo quality, we cannot exclude the possibility that small differences in starting quality between embryos may have contributed to the differences observed, other than the addition of SMs. WIDER IMPLICATIONS OF THE FINDINGS This approach would allow the establishment of autogeneic or allogeneic matched cells from embryos fertilized in vitro without destroying them.

Abstract
Here, we present a highly efficient and reproducible method for the establishment of mouse embryonic stem cells (mESCs) from embryonic day 3.5 (E3.5) whole blastocysts. This protocol involves the use of small molecules SB431542 and PD0325901, which inhibit transforming growth factor-β (TGF-β) and extracellular signal-regulated kinases (ERK1/2), respectively. This protocol is universal in the derivation of mESC lines from NMRI, C57BL/6, BALB/c, DBA/2, and FVB/N strains, which have previously been considered refractory or non-permissive for ESC establishment. The efficiency of mESC lines generation is 100%, regardless of genetic background.

Abstract
We describe a new, efficient protocol that involves the serial addition of noggin, basic fibroblast growth factor (bFGF), retinoic acid, and sonic hedgehog (Shh) for the differentiation of human induced pluripotent stem cells (hiPSC) to retinal pigmented epithelium (RPE) in a serum- and feeder-free adherent condition. hiPSC-RPE cells exhibited RPE morphology and specific molecular markers. Additionally, several hiPSC lines were generated from retinal-specific patients with Leber's congenital amaurosis, Usher syndrome, two patients with retinitis pigmentosa, and a patient with Leber's hereditary optic neuropathy. The RPE cells generated from these disease-specific hiPSCs expressed specific markers by the same RPE lineage-directed differentiation protocol. These findings indicate a new short-term, simple, and efficient protocol for differentiation of hiPSCs to RPE cells. Such specific retinal disease-specific hiPSCs offer an unprecedented opportunity to recapitulate normal and pathologic formation of human retinal cells in vitro, thereby enabling pharmaceutical screening, and potentially autologous cell replacement therapies for retinal diseases.

Abstract
Malignant tracheoesophageal fistula occurs infrequently in patients with irradiated esophageal and lung cancer, uncommonly in patients with untreated mediastinal malignancies, infection, or trauma, and rarely in primary adenocarcinoma of the lung. The natural progression of this entity leads to rapid deterioration and death from overwhelming pulmonary infection.Definitive treatment depends on the demonstration and localization of the fistula. Computerized tomography (CT) chest scanning with dilute oral contrast is the ideal means of identification of the fistula. CT scanning without contrast may outline sufficiently the pathology to avoid the usage and side effects of contrast media in the lungs.A review of one case of tracheoesophageal fistula due to pulmonary adenocarcinoma is presented where emergency CT scanning without contrast resulted in rapid and accurate diagnosis, leading to prompt and appropriate management.

Abstract
Fibroleiomyomatous hamartoma of the lung is an extremely rare, nonneoplastic overgrowth of pulmonary muscle tissue which can be found in various sites throughout the lung. Several cases have been previously described. The case presently reviewed demonstrates the multinodular form of this entity. Fibroleiomyomatous hamartoma may also appear as a solitary coin lesion or as a diffuse interstitial pattern on chest radiographs.

Abstract
Pericardial effusion has a variety of causes. Among these, inflammatory processes are the most common. Traditionally x-rays, isotopic scanning, carbon dioxide injection, and M-mode echocardiography have been used for evaluation of pericardial effusion. The most recent advance in real time scanning enables the examiner to more completely and more accurately evaluate and serially investigate pericardial effusions through a noninvasive technique.

Abstract
Material from three years of experience with a real time contact ophthalmic scanner is presented. Routine screening of patients with cataracts revealed unsuspected retinal detachments and advanced vitreous hemorrhage in a significant percentage. Foreign bodies near the posterior ocular wall were optimally evaluated by both radiographic and ultrasonic localization methods to avoid the inherent error of the x-ray triangulation system. The traumatized eye may be effectively studied for internal damage by using a thick layer of methyl cellulose without putting pressure on the globe. Many types of vitreous and retinal pathology may be confirmed or better evaluated by this simple, noninvasive technique.
